Managing Liabilities at Manufactured Gas Plant Sites

Since 2001, Geosyntec has assisted We Energies with environmental issues related to the redevelopment of a former manufactured gas plant site. To learn more about this project, please see our Assessment and Engineering Services for the Redevelopment of a Former Manufactured Gas Plant Site

Strategic Approaches to MGP Sites

Geosyntec professionals have comprehensive experience investigating and remediating former manufactured gas plants (MGPs), stakeholder negotiations, development of remedial strategies, serving as expert witnesses, and otherwise assisting with litigation. Services include site investigation, feasibility studies, development and implementation of remedial action plans, evaluation of treatment options, value engineering as part of a third party review of another firm's work, assessment and mitigation of subsurface vapor intrusion pathways, and site closure.

Innovative Technologies for MGP Sites

Geosyntec defines the state of the practice in many fields because of our strong academic >and research interests. One example of our innovative technological approaches is STAR: (Self-sustaining Treatment for Active Remediation). STAR is an innovative technology to remediate Non-Aqueous Phase Liquids (NAPLs) which uses smoldering combustion to quickly and efficiently destroy contaminants. Another example is our Corrective Action Plan (CAP) for site and stream remediation and reduction of hydrocarbons using an air sparging fence in a fractured bedrock aquifer.

STAR

Self-sustaining Treatment for Active Remediation (STAR) is a new remediation approach with the potential to combine technical effectiveness, quick treatment, and substantial savings in operation and maintenance costs relative to currently available techniques. STAR is provided by our environmental technology research & testing laboratory SiREM, a wholly owned subsidiary of Geosyntec. Learn More
